Parameters > Citect.ini File Parameters > Trend Parameters > [Trend]AcquisitionTimeout


Sets a timeout to stop a trend server waiting indefinitely for a valid data sample from an I/O device while the connection to the I/O server is lost or the device is offline.

On each sample collection, the gap between current time and the last sample request time is checked. If this gap is greater or equal to the value set for this parameter, and the sample data is invalid, a gap fill action is requested (i.e. synchronization will be performed). This implementation is designed to avoid large gaps in trend history when the connection to an I/O device is lost.

Allowable Values: 0 to 65536 (seconds)

Default Value: 300 (seconds)
